Title: What needs the Eagle treatment?
Post by: jubal81 on August 19, 2012, 07:50:55 PM
It's a lazy, rainy Sunday and I want to do a little layout work. Problem is, I need a good idea for a circuit in need of a board. Any suggestions?

Dry/Wet mix control for insertion to existing circuits.

A prototype board for that is already on its way.  ;)

Jacob has a blend control in the members section.

How about Azabache by run off groove, or the dod 440.

New ROG looks cool. I'm pretty sure they wouldn't like me making boards for it, though. The 440 is neat, too, but the Nautilus is just around the corner and I'm chomping at the bit for that one.

I've pulled up the OD-820 from Maxon and I'm thinking about doing that one.

Did up the OD-820 and should have the boards in a few weeks. I'm already working on a slimmed-down version that simplifies the charge pump and uses a quad opamp instead of two 4558s.

Awesome!

That will be very welcome, indeed.  Klonkiller!  ::)
I think you would have very positive reaction from a board for the Distortion Master also.  Was it the
DS-830?
Schem is on FSB, or I have it in my stash, if needed.

Your layout looks fantastic! You must be practicing?
Gotta learn EAGLE...

Finally got back around to doing some debugging. I had one pot reversed in the schematic and had the input buffer jfet pinout wrong.

This thing sounds really, really good. It's a very uncompressed, mild-to-mid gain overdrive and stays musical with aggression. (I know, I hate trying to describe tone)
Mucho Macho is definitely getting boxed up.

May have been covered already... but is a parametric EQ out of the question?

Nope. It does use dual pot, clean-blending ala Klone.

I think he's referring to the original question...

Parametric EQ is not out of the question. I think R.G has some info on GEOFEX that you could look into. If'n I'm not mistaken, Austin/Coldcraft/AZiltz was looking into this with me aaaages ago. We sorta lost interest.

You're correct.  I know there's a couple of vero/strip layouts floating around, but I have yet to see a nice, elegant parametric EQ pcb anywhere.

I'm working on a vero 820 right now. Is that REALLY at 470uf cap? Sheesh!  :o

Cool. I'd like to hear what you think of it. That's just a power cap. I'm sure a smaller one won't matter.

What transistor are you using in place of the 2SK246?

Finished the circuit today. Baby is sleeping so I only got a chance to play through headphones. Sounds very very very close to the Klon. I would not be able to pick which is which if I was blind folded. They vero layout is a little uncomfortable but it works. No enclosure yet, just playing through my testing rig.  I also built a Maxon 808 on vero and I really like it....better than the 820. I ended up using a 2N5457 for the 820.

2N5457 here, too. It does sound very klon-like, but less compressed to my ears. Really it sounds even more like Bean's Kingslayer with the diodes in the feedback loop.
